Course Introduction：The method to change the interface language in Photoshop is as follows: 1. Open Photoshop and click "Edit" in the top menu bar; 2. Select "Preferences" > "Interface"; 3. Select the desired language in the "User Interface Language" drop-down menu, and restart the software to take effect. This feature is only applicable to installation packages that support multilingual versions. If the option is not available, it may be that a single language version is installed.

You need to pay attention to interface consistency issues when collaborating.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
